AMPTS III and AMPTS III Light consist mainly of three parts: Incubation unit, CO
unit and detection unit (also called gas volume measuring device).
1) Incubation Unit (Unit A): Here is where the fermentation process takes place (Figure
3). 18 (0.5 or 1 L) or 9 (2 L) reactors are placed inside a thermostatic water bath (68 x
56 x 33 cm), which is used for temperature control (up to 60° C, precision of 0.2° C).
The thermostatic water bath is provided with a lid for 18 or 9 reactors to minimize
water loss and ensure that the temperature set point is rapidly reached. The
incubation system provides a well-controlled environment in regard to temperature,
pH, and relative humidity for biogas/biohydrogen production.

Each reactor is connected to a brushless DC motor that ensures a well-mixed content
through a strong, reliable, and multifunctional agitation system (Figure 4). A motor
controller provides the power via motor cables, where all the motors receive the same
information. The MCU needs to be turned off and unplugged from the power source
when any cables are connected or disconnected from the motors.
